A 1.2 Ma record of glaciation and fluvial discharge from the West European Atlantic margin ArchiMer
Toucanne, Samuel; Zaragosi, S.; Bourillet, Jean-francois; Gibbard, P. L.; Eynaud, F.; Giraudeau, J.; Turon, J. L.; Cremer, M.; Cortijo, E.; Martinez, P.; Rossignol, L..
The correlation of continental sedimentary records with the marine isotope stratigraphy is a challenge of central importance in Quaternary stratigraphy, particularly in Western Europe where long records of glaciation on land areas are particularly rare. Here we demonstrate for the first time the interrelationship of events during the last 1.2 Ma in an ocean-sediment core from the Bay of Biscay (NE Atlantic), SW of the Channel. The identification of discharge variations from tributary river systems to the 'Fleuve Manche' palaeoriver during glacio-eustatic sea-level lowstands demonstrates the correlation of the marine sediment stratigraphy to the expansion and recession of the European ice-sheets. The amplitude and chronology of European ice-sheet...

A bioüzemanyagok használatával járó várható földhasználati változások Magyarországon AgEcon
Vida, Adrienn; Baksa, Adrienn.
Az egyre növekvő energiafelhasználás, világnépesség és éhezés olyan, több évtizede megoldatlan problémák, amelyeket a klímaváltozás és az ez által kialakult szélsőséges időjárási viszonyok tovább súlyosbítottak, a napjainkban tapasztalható gazdasági válság pedig még inkább megnehezítheti megoldásukat. A megújítható energiaforrások szerepének növelésében katalizátorszerepet betöltő Európai Unió már a 80-as évek elején megoldást keresett a túltermelés következtében felhalmozódott szántóföldi termékek felhasználására. Az idők során a támogatási rendszer is a non-food termelést helyezte egyre inkább előtérbe, majd a kialakított direktívák és piaci intézkedések előkészítették, és így biztosították az összefoglalóan biomasszának nevezett megújítható...

A Case for Developing Place-Based Fire Management Strategies from Traditional Ecological Knowledge Ecology and Society
Ray, Lily A; Department of Geography, Clark University; Resilience and Adaptation Program, University of Alaska, Fairbanks ; lray@kawerak.org; Kolden, Crystal A; Department of Geography, University of Idaho; ckolden@uidaho.edu; Chapin III, F. Stuart; Institute of Arctic Biology, University of Alaska, Fairbanks ; terry.chapin@alaska.edu.
Sustainability science promotes place-based resource management because natural processes vary among ecosystems. When local science is limited, land managers may be forced to generalize from other ecosystems that function differently. One proposed solution is to draw upon the traditional ecological knowledge that indigenous groups have accumulated through resource use. Integrating traditional ecological knowledge with conventional resource management is difficult, especially when the two offer competing explanations of local environments. Although resource managers may discount traditional ecological knowledge that contradicts conventional resource management, we investigate the possibility that these disagreements can arise when nonlocal resource...

A cognitive psychological approach of analyzing preference uncertainty in contingent valuation AgEcon
Akter, Sonia; Bennett, Jeffrey W..
The sources of preference uncertainty in contingent valuation (CV) studies have rarely been investigated from a theoretical standpoint. This paper proposes a holistic theoretical framework of preference uncertainty that combines microeconomic theory with the theories of cognitive psychology. Empirical testing of the proposed theoretical model was carried out in Australia in the context of a national ‘Carbon Pollution Reduction Scheme (CPRS)’ to be introduced in 2010. Two separate ordered probit models for a certainty score associated with CV ‘Yes’ and ‘No’ responses were estimated. The results of the estimated regression models provide evidence supporting the hypotheses drawn from the theoretical model.

A conceptual model to describe heat stress in dairy cows from actual to questionable loops Acta Agron. (Palmira)
Molina Benavides,Raúl Andrés; Sánchez Guerrero,Hugo; Atzori,Alberto Stanislao.
Abstract Thermal environment is recognized to be one the most important ecological factor to determine domestic animal growth, development and productivity for direct and indirect effects on its physiology and behavior. Despite having specific and individual adaptation, is very common, within seasonal or diurnal temperature variations, animals deal with situations outside their thermal comfort zone. Due to heat stress, dairy cows reduce milk production and fertility, and therefore, had achieved an increasing in metabolic disorders incidence, causing low revenues to farm in short and medium periods. Due to world climate change more impact of the meteorological variables on animal responses is expected for the future. This study aimed to describe and...

A cultural landscape approach to community-based conservation in Solomon Islands Ecology and Society
Walter, Richard K; University of Otago; richard.walter@otago.ac.nz; Hamilton, Richard J; The Nature Conservancy, Asia Pacific Division; ARC Centre of Excellence for Coral Reef Studies, James Cook University; rhamilton@tnc.org.
International environmental organizations have an increasing commitment to the development of conservation programs in high-diversity regions where indigenous communities maintain customary rights to their lands and seas. A major challenge that these programs face is the alignment of international conservation values with those of the indigenous communities whose cooperation and support are vital. International environmental organizations are focused on biodiversity conservation, but local communities often have a different range of concerns and interests, only some of which relate to biodiversity. One solution to this problem involves adoption of a cultural landscape approach as the ethical and organizational foundation of the conservation program. In our...

A fenntartható fejlődést szolgáló paradigma AgEcon
Meszaros, Sandor.
Az uralkodó neoklasszikus paradigma alapján a 20. század második felében a gazdasági növekedés a várható klímaváltozás, a Föld természeti erőforrásai és a társadalmi egyenlőtlenségek figyelembevétele nélkül ment végbe. Erre a helyzetre szolgált válaszul a fenntarthatóság koncepciója, amely az utóbbi két évtizedben globális mozgalommá vált, és nemzeti alkalmazkodási stratégiák kidolgozásához vezetett. A gazdaság működésére azonban igazán új paradigma mégsem született, bár a köz¬gazdaságtan a komplexitás irányába látszik fejlődni. Az új (transzdiszciplináris) paradigma eddigi hiánya ellenére a szükséges változások irányai már felismerhetők: a fosszilis energiaforrások mielőbbi helyettesítése és az erdőgazdaság kiemelt kezelése (Low Carbon Economy), valamint...

A fitopatologia nos cenários de aquecimento global. Repositório Alice
LOPES, C. A..
O objetivo deste capítulo não é de ser mais uma revisão sobre o tema em patossistemas específicos, e sim de comentar informações sobre assuntos relacionados à epidemiologia e controle de doenças de plantas diante da eventual perspectiva do aquecimento global. O desenvolvimento do tema é organizado, para fins didáticos, nos conceitos da epidemiologia, definida como "qualquer mudança na intensidade da doença, numa população de hospedeiros, no tempo e no espaço" (AMORIM et al., 2011). Dessa maneira, os fatores "patógeno" e "hospedeiro" são influenciados pelo componente "ambiente".

Summary: The effective impact of climate changes on the coffee plant physiology, promoted by enhanced air [CO2] and global warming remain to be fully elucidated through biological studies. Therefore, this work aims at linking important coffee physiological responses to environmental changes of enhanced growth [CO2] and temperature on genotypes from the two major producing species. Potted plants from C. arabica cv. IPR 108 and of C. canephora cv. Conilon Clone 153 were grown under environmental controlled conditions, either at 380 or 700 ?L CO2 L-1 air, for 1 year, without water, nutrient or root development restrictions. After that the temperature was gradually increased from 25/20 ºC (day/night) up to 42/34 ºC. The long-term impacts of enhanced growth...

A mezőgazdasági területek érzékenységének és adaptációs képességének mérési lehetőségei AgEcon
Farkas-Fekete, Maria.
A tanulmány alapvető célja az, hogy hozzájáruljon az érzékenység, sérülékenység és adaptációs képesség vizsgálatának módszertanához. A kutatások eredményei felhívják a figyelmet arra, hogy bár az európai vidék összessége egyre sérülékenyebbé válik a különböző globális kihívásokra, a veszélyeztetettség mértéke régiónként eltérő. A kutatások eredményei megerősítették az IPCC 3. jelentésében megfogalmazott hipotéziseket, melyek szerint a gazdag országok ugyanolyan veszélyeztetettség mellett is kevésbé sérülékenyek, mivel nagyobb az alkalmazkodóképességük. A klímaváltozás, amely pozitív és negatív hatást is gyakorol Európa mezőgazdaságára, módosítja az eddigi komparatív előnyöket, illetve hátrányokat. Gazdasági szempontból Dél- és Közép-Kelet-Európa minden...

A multi-period positive mathematical programming approach for assessing economic impact of drought in the Murray-Darling Basin, Australia AgEcon
Qureshi, Muhammad Ejaz; Ahmad, Mobin-ud-Din; Whitten, Stuart M.; Kirby, Mac.
In the last decade, the Murray-Darling Basin (MDB), Australia faced a severe drought which affected its agriculture production. Sustainable diversion limits as proposed in the Australian Government’s basin plan together with climate change is expected to impact on future agriculture production and development in the MDB. We developed a biophysical-economic mathematical model calibrated against the observed multi-period land use data utilising the positive mathematical programming (PMP) approach to evaluate the impacts on agricultural production activities of a range of climate events and policy options. This is an extension of our previous work where the model was calibrated against a single year and focus was on the southern MDB only. The multi-period...

A new method to simulate the hydrological state of soil under natural conditions. Repositório Alice
WILD, A.-K; MARX, M. T.; EISENBEIS, G..
Abstract ? Micro, macro and mesofauna in the soil often respond to fluctuating environmental conditions, resulting in changes of abundance and community structure. Effects of changing soil parameters are normally determined with samples taken in the field and brought to the laboratory, i.e. where natural environmental conditions may not apply. We devised a method (STAFD ? soil tubes for artificial flood and drought), which simulates the hydrological state of soil in situ using implanted cores. Control tubes were compared with treatment tubes in which floods of 15, 30, 60 and 90 days, and droughts of 60, 90 and 120 days were simulated in the field. Flooding and drought were found to reduce number of individuals in all soil faunal groups, but the response to...

A Ricardian analysis of the impact of climate change on African cropland AgEcon
Kurukulasuriya, Pradeep; Mendelsohn, Robert.
This study examines the impact of climate change on cropland in Africa, using a Ricardian cross-sectional approach. Relying on farm data from an 11-country survey of over 9500 farmers, annual net revenue is regressed on climate and other variables. The study confirms that current climate affects the net revenues of farms across Africa. Applying these results to possible future climates reveals that dryland farms are especially climate sensitive. Even as early as 2020, climate change could have strong negative impacts on currently dry and hot locations. By 2100, dryland crop net revenues could rise by 51% if future warming is mild and wet but fall by 43% if future climates are hot and dry. The crop net revenues of currently irrigated farms are likely to be...

A Ricardian Analysis of the Impact of Climate Change on South American Farms Chilean J. Agric. Res.
Niggol Seo,S; Mendelsohn,Robert.
This study estimates the impact of climate change on South American agriculture taking into account farm adaptations. The study used a Ricardian analysis of 2300 farms to explore the effects of global warming on land values. In order to predict climate change impacts for this century, were examined climate change scenarios predicted by three Atmospheric Oceanic General Circulation Models (AOGCM): the Canadian Climate Center (CCC), the Centre for Climate System Research (CCSR), and the Parallel Climate Model (PCM) models. Several econometric specifications were tested, and five separate regressions were run: for all farms, small household farms, large commercial farms, rainfed farms, and irrigated farms. Farmland values will decrease as temperature...

A Structural Land-Use Analysis of Agricultural Adaptation to Climate Change: A Proactive Approach AgEcon
Kaminski, Jonathan; Kan, Iddo; Fleischer, Aliza.
This article proposes a proactive approach for analyzing agricultural adaptation to climate change based on a structural land-use model wherein farmers maximize profit by allocating their land between crop-technology bundles. The profitability of the bundles is a function of four technological attributes via which climate variables‟ effect is channeled: yield potential; input requirements; yields' sensitivity to input use; and farm-level management costs. Proactive adaptation measures are derived by identifying the technological attributes via which climate variables reduce overall agricultural profitability, despite adaptation by land reallocation among bundles. By applying the model to Israel, we find that long-term losses stem from yield potential...

About the origin of the Mediterranean Waters warming during thetwentieth century ArchiMer
García-martínez, María Del Carmen; Vargas-yáñez, Manuel; Moya, Francina; Zunino Rodriguez, Patricia; Bautista, Begoña.
The Mediterranean Sea transforms Atlantic Waters inflowing through the Strait of Gibraltar into saltier, cooler and denser Mediterranean Waters that outflow into the Atlantic Ocean. A theoretical steady state functioning of the Mediterranean Sea would be the result of the balance between the net heat and volume transports through the Strait of Gibraltar and the heat loss to the atmosphere through the sea surface and the net evaporation. The salt transport for the inflow and outflow should be balanced. Changes in the heat content, temperature and salinity of the Mediterranean waters reveal that the present Mediterranean functioning is out of this equilibrium state. A new analysis for MEDAR data shows that the temperature and salinity averaged for the...
